BTW now the screen also gets stuck as black-screen when I close my laptop lid, wait some seconds and open it again.
And the functions keys to regulate screen brightness are working no more (I also tried to change brightness with this tool http://ubuntuhandbook.org/index.php/2017/05/install-brightness- controller-utility-in-ubuntu-16-04-higher/ but it had no effect ...) Could this be related to the above described issue?
